prevent C++ locale number formatting in text APIs

prevent C++ locale number formatting in text APIs

Setting the C++ locale via std::locale::global(std::locale("")); which
would otherwise default to the default C locale (aka: unaffected by
setlocale) effects the formatting of numeric types in IO streams, which
for output for humans is perfectly sensible, but breaks our many text
interfaces used and parsed by us and others without expecting the
numbers to be formatted.
